Morrowind and Half Life are my favourites. I've been disappointed by Oblivion - I don't like the enemies scaling with you. What I loved about Morrowind was that you had to really level up before you could go and explore half the map - and Oblivion missed that. I'm holding out for Skyrim!

I used to play World of Warcraft but stopped before the new expansion.
Now I am waiting for Portal 2 and Dota 2,like many of you. :)
Heroes of Newerth is really good too.
Still playing Mario Kart or Smash Bros on Wii with friends at home,or set up my Nintendo 64 and play some Zelda.
